Professional Precision Torque Tool – Built for Reliability

As a dedicated manufacturer with over 20 years of experience, Cangzhou Dean Safety&Special Tools Co.,Ltd delivers this high-performance Adjustable Self-Locking Torque Wrench designed for demanding environments. With a torque range of 10–150 Nm and a 72-tooth ratchet mechanism, this tool provides precise fastening control while minimizing operator fatigue. Whether you are assembling automotive components, tightening industrial machinery, or performing routine maintenance, our torque wrench offers the consistency and durability you need. Each unit undergoes rigorous factory calibration to ensure ±3% accuracy, giving you confidence in every turn.

Key Features & Technical Specifications

Self-Locking Adjustment: The patented push-pull collar securely locks the selected torque value, preventing accidental changes during use. No separate lock rings or buttons required.
72-Tooth Ratchet: With a mere 5° swing arc, the ratchet head allows operation in tight spaces where conventional wrenches cannot fit. This improves work efficiency and reduces wrist strain.
Wide Torque Range (10–150 Nm): Covers a broad spectrum of applications from delicate electronics to heavy machinery. Scales are clearly marked in both Nm and ft-lb (dual scale available upon request).
Rugged Construction: Made from heat-treated chrome vanadium steel (CR-V), the wrench body resists wear and corrosion. The phosphate-coated finish provides additional protection in oily or humid conditions.
Audible Click & Tactile Feedback: When the preset torque is reached, the wrench emits a distinct click sound and a slight impulse, signaling the operator to stop – no need to watch a gauge.
Reversible Ratchet Head: For both clockwise and counterclockwise tightening, simply flip the reversing lever. Suitable for left-hand threads and loosening tasks.
Calibration Certificate: Each tool is shipped with a traceable calibration certificate (factory calibrated to ISO 6789:2017 standards, optional third-party certification available at extra cost).

Benefits for Your Operation

Reduced Rework & Damage: The self-locking mechanism and ±3% accuracy eliminate over-torquing and under-torquing, protecting threads and components. Less scrapped parts = lower costs.
Faster Workflow: The 72-tooth ratchet and audible click allow operators to work quickly without constantly checking a scale – ideal for high-volume assembly lines.
Ergonomic Design: The comfortable non-slip handle reduces hand fatigue during repetitive use. A knurled grip area ensures secure holding even with oily gloves.
Universal Compatibility: The 1/2 inch drive fits standard sockets and extensions. Optional drive sizes are available to match your specific tool set.
Long Service Life: The CR-V construction and phosphate coating resist rust and impact. With proper care (storage in provided case), this wrench can serve for years.

Frequently Asked Questions (FAQ)

How do I adjust the torque setting on this wrench?
First, pull the locking collar upward (toward the handle) to release the lock. Then rotate the handle to the desired torque value as shown on the scale. Release the collar, and it will snap back into place, locking the setting. A slight rotation of the handle confirms engagement.
Is the wrench pre-calibrated before shipment?
Yes, each tool is factory calibrated to ±3% accuracy in the clockwise direction. A calibration certificate is included with the package. For higher precision or third-party certification, please inquire about our optional calibration services.
Can I use this wrench for both tightening and loosening?
Yes, the ratchet head is reversible. Simply flip the lever on the head to switch between clockwise (tightening) and counterclockwise (loosening) operation. Note that accuracy is specified for clockwise tightening only.
What drive size and socket compatibility does this wrench have?
The standard configuration is a 1/2-inch square drive, which fits most standard sockets and accessories. We also offer 3/8-inch drive and 1/4-inch drive options upon request. Please specify your preference when ordering.
How durable is the 72-tooth ratchet mechanism?
The ratchet is made from hardened steel and has a 5° swing arc, allowing use in confined spaces. It is built to withstand repeated heavy loads. However, like all precision tools, avoid using extensions or cheater bars that exceed the wrench's maximum torque rating (150 Nm).
Does the wrench come with a storage case?
Yes, each torque wrench is supplied with a blow-molded plastic case to protect the tool during transport and storage. Custom packaging (e.g., foam insert, branded case) is available for bulk orders.
What are the available customization options for OEM orders?
We can customize the laser engraving (logo, text), torque range scale (Nm, ft-lb, in-lb), handle color, drive size, overall length, and packaging. Minimum order quantity may apply. Contact our sales team for details.
How should I store the torque wrench to maintain accuracy?
Always store the wrench in its case, with the torque setting returned to the lowest value (10 Nm) to relieve spring tension. Keep it in a dry, clean environment away from extreme temperatures. Calibration is recommended annually for professional use.
